  • Sedimentary rock - Wikipedia

    Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface Sedimentation is the collective name for processes that cause these particles to settle in place The particles that form a sedimentary rock are called sediment.
